Is It Safe To Use A Cloudy Hot Tub Water

As a hot tub owner, your top priority should be the safety and hygiene of those who use it. Therefore, it is not safe to use cloudy, hot tub water. 

When there is cloudy hot tub water, it indicates that small particles are floating around, and the filters are not enough to remove them. This means that the water is not clean and hygienic and can cause skin irritations and infections. 

Cloudy water can also indicate an unbalanced level of chemicals, which can be dangerous to your health. Therefore, ensure the water is crystal clear before using your hot tub. 

If the water is cloudy, follow the steps to clean it. Remember that a clean hot tub ensures a healthy hot tubing experience. 

What Are The Reasons For Cloudy Hot Tub Water

Several reasons can make your hot tub water. One of the most common causes is imbalanced chemical levels, particularly high pH, high alkalinity, and low sanitizer levels. 

These elements help regulate the cleanliness and clarity of the water, so maintaining proper levels is crucial. When these elements’ levels lose balance, the tub water can become cloudy.

Dirty filters, old water, and body care products like lotions and oils can also make the water cloudy. Another reason for cloudy water is when a lot of people are using your hot tub; it can also affect water quality. 

Proper maintenance and regular cleaning can help keep cloudy water at bay and ensure a safe and enjoyable soaking experience.

Ways To Clean The Cloudy Hot Tub Water

Your hot tub is a perfect element to relax and remove all your stresses. But all these pleasant feelings can wash away if you see your hot tub water becoming cloudy. No doubt you will lose interest in soaking. 

Earlier, we discussed the reason why the water could become cloudy. There are several ways to remove this cloudiness from the water. Let’s see what they are:

1. Check The Chemical Level And Solve It

One of the most important steps to clearing up cloudy, hot tub water is to check the chemical levels and solve any imbalances. You must maintain the ideal sanitizer level, as it is crucial to keep the water safe, clean, and clear. 

You can use test strips or drop-style kits to check the water’s pH, alkalinity, sanitizer, and calcium levels and adjust them accordingly. When the water chemistry is balanced correctly, it can prevent staining, scale buildup, and cloudy water. 

If minerals cause the problem, you may need to use a metal sequestrant. You can also apply shock treatment with a chlorine or bromine sanitizer to eliminate the organic matter. 

You must add sanitizer as the required amount. This will depend on your test strip results, and you should shut off the air valves when adding chemicals. 

Checking and cleaning the filters also play a significant role in preventing cloudy water. You can rinse and treat the filters with a filter cleaner periodically to remove oils and greases. 

2. Check Ph Level And Alkalinity Levels

You should check the pH level and alkalinity levels of your hot tub water, as it is crucial for maintaining clear and safe water. The pH level measures the acidity or basicity of the water and should be between 7.2 and 7.8.

 If the pH level is too high or too low, it can cause a range of issues, such as eye or skin irritation, scale formation, and poor chlorine efficiency. Your hot tub water can become cloudy when the pH level becomes imbalanced.

The alkalinity level measures substances in the water, such as hydroxides, carbonates, and bicarbonates. These elements should measure between 80 to 150 parts per million. You can prevent cloudiness and bacteria growth by keeping the alkalinity level balanced.

You should always check the pH and alkalinity levels before adding any sanitizer or chlorine-free shock treatment. Doing this ensures that the chemicals are effective and the water remains safe for use.

3. Shock Treatment

You can try shock treatment if you find yourself dealing with cloudy, hot tub water and the cloudy water is bothering you too much. 

To apply this treatment, you need to add a large amount of sanitizer, such as chlorine or bromine, to the water to eliminate any organic matter and bacteria that may be causing the cloudiness. 

You can also apply non-chlorine shock treatments; it’s also available if you prefer to avoid chlorine. You can also improve the overall sanitation of the water, trapping and removing any contaminants by shocking your hot tub water.

However, you should be cautious when using shock treatment, as adding too much can worsen the cloudiness and harm the hot tub’s plumbing and equipment. 

To avoid this kind of incident, follow the instructions carefully and consult a professional if you have any concerns or questions. With the right approach, shock treatment can effectively clear up your hot tub water and restore it to sparkling clarity.

4. Use Water Clarifier

You can use a water clarifier to clear up cloudy hot tub water; it is another effective solution. This process works by clumping together all the small particles, making them easier to filter out of the water. 

You must use the correct amount and not overdose the clarifier, which can worsen the problem. A water clarifier is a good option, especially if you have tried other methods unsuccessfully. 

However, you should not use the clarifier as a regular solution to maintain clean hot tub water. Instead, it should be used occasionally to treat cloudy water. 

Additionally, always follow the manufacturer’s instructions when using a water clarifier to achieve the best results.

5. Drain The Cloudy Water And Refill Hot Tub

When all the above techniques fail, and your hot tub water won’t clear up, you may need to drain the water and start fresh. 

Sounds like quite a hassle? Don’t worry; it can be a good idea to do it every few months, even if you don’t have cloudy water. When you drain and refill your hot tub with fresh water, you get rid of any buildup of contaminants and minerals that can affect the quality of your water. 

When you drain the cloudy water, it’s actually an excellent opportunity to clean the surfaces of your tub and give it a deep cleaning. 

You can save some money in the long run when you start with fresh water because you won’t need to use as many chemicals to keep your water balanced and clean. 

Remember to follow proper draining and refilling procedures and properly sanitize your hot tub before using it again.
